This doesn’t seem to be a topic that has been fully discussed. I think it is kind of useful for some.

For the hot flashes and night sweats I got an Embrlabs.com Wave 2 device. I used to wake up with a sheet totally soaked under me. The wave device stopped that.. The wave 2 Has two buttons and you can set one for Hot flashes during the day and one for night.

They normally cost $300 with this code you can get one for $200 BFCM25. They have 60 day money back guarantee.

If you get one, post on here and I can give you instructions for how to configure it the best way. They have added options to the app so that you can schedule different cooling needs. You could schedule it to automatically cool you at night instead of using the buttons.

The tissue in the penis can deteriorate a lot if it’s not used for a long time. Five months is not a long time. A lot of doctors give their patient Cialis to take daily after having treatments, That can help restore the flow of blood. You might ask your doctor about this, it could help.

You can also use injections like Trimix Which can get a good erection.

A low testosterone will give you no libido. In the next few months, yours should start to rise. Four months of Lupron is almost nothing, your testosterone should start coming back pretty quickly.

Just to let people know, the discount code for the Embrlabs wave2 device has expired.

Neither my Oncologist nor my Urologist told me I would lose my ability to ejaculate after my radiation. It is basically like having your man card taken away. My erections are also not what they were but I don't take anything since the anejaculation makes me unwilling to engage in sex anyway. Before my diagnosis and treatment I was extremely sexually active. Now I may as well be living in a cave. I think people should be aware of those conditions going in. I wasn't.

I received SBRT (9/2024) and remain on ADT (planned 12-18 mos) for Gleason 9 (4+5) localized disease. I was placed on tamsulosin for urinary retention during RT which I have continued, knowing that it caused retrograde ejaculation for me when used previously for BPH (which resulted in my discontinuing the medication then). I was warned that after RT I would have dry ejaculation with or without Tamsulosin. ADT suppresses my libido and makes erections more difficult to attain and orgasm more difficult to achieve. I was warned about all of these issues by both the urologist and radiation oncologist when deciding on treatment options. I have no regrets; my PSA is down from 15.3 ng/ml prior to treatment to 0.18 ng/ml only 10 weeks after radiation was completed. The sexual side effects are frustrating but with the help of my spouse I am able to enjoy our intimacy even without penetrative sex. I hope when ADT is completed that my cancer remains controlled and my sex life improves though I do not expect it to be the same as it was before.

You can’t ejaculate, but you can climax. That’s really what people are looking for.

@mouser26 After radical prostatectomy my climax changed. I didn't have ejaculate which "primed the pump" but I have learned to be aware of the arousal is in the mind. I can still climax but the feeling is more in the pelvic muscles. Yes it is different but still satisfying. I don't have any erections since my surgery in July 2025 but it is SLOWLY getting better. I have been will likely take up to a year or more to get erections again but I"ve adapted in my mind to accept the new norm and if it improves over the next year, even better... My .04 PSA after prostatectomy suggests this will be a treatable condition, not a death sentence, in the future.....

Crazy how all cases are different. I get good solid erections (2 months post RARP), but no orgasms.
